Honda's short-term fuel consumption suddenly increased (from 6.0 to 8.2)

Engine carbon deposit. Long-term operation of automobiles will inevitably produce carbon deposits and sludge during the combustion of gasoline. If these sludge and carbon deposits are not cleaned up in time, the fuel consumption of automobiles will increase. Therefore, it is also important to clean up the engine carbon deposit in time. Spark plug failure. The function of automobile spark plug is to use high voltage electricity to generate electric spark to ignite the mixture. If it is damaged, the ignition energy will be reduced, and the mixture will burn unevenly, which will lead to the slow speed increase and the increase of fuel consumption. At this time, it is necessary to check and replace the spark plug in time.

The tire pressure is abnormal. Abnormal tire pressure will also have an impact on automobile fuel consumption. When the tire pressure is too low or the tread is seriously worn, the contact area between the tire and the road surface becomes larger, the friction force increases, the rolling resistance increases, and the fuel consumption naturally increases. Of course, on the other hand, high tire pressure has a certain fuel-saving effect, but in this way, the shock absorption comfort of the car will become worse, and there will be hidden dangers of puncture. Sensor failure. The fault of automobile sensor is also the main reason for the increase of automobile fuel consumption. When the water temperature sensor fails, the engine mistakenly thinks that the car is in a cold state and will always send fuel injection information, resulting in an increase in fuel consumption of the car. In addition, the failure of oxygen sensor steam and air flow meter will also lead to the increase of automobile fuel consumption.
